FractGen is a simple Qt-based fractal generator program for Mandelbrot fractals. The image size is only limited by virtual memory. It is possible to zoom into images. Image parameters are saved in and loaded from XML-encoded FractGen Settings Files (FSF). Calculated images can be exported as graphics files. The intention of this program is to generate graphics to be post-processed by other image tools, e.g. in order to generate nice screen backgrounds or book covers.
